| 21 | # Browser Automation Skill |
| 22 | |
| 23 | Web browser automation using agent-browser with AI-optimized snapshots. Reduces context by 93% using element refs (@e1, @e2) instead of full DOM. |

| 26 | |
| 27 | ```bash |

| 32 | agent-browser snapshot -i # -i = interactive elements only |
| 33 | |
| 34 | # 3. Interact using refs from snapshot |
| 35 | agent-browser click @e2 |
| 36 | agent-browser fill @e3 "text" |
| 37 | |

| 169 | ## Integration with Claude Flow |
| 170 | |
| 171 | ### MCP Tools |
| 172 | All browser operations are available as MCP tools with `browser/` prefix: |
| 173 | - `browser/open` |
| 174 | - `browser/snapshot` |
| 175 | - `browser/click` |
| 176 | - `browser/fill` |
| 177 | - `browser/screenshot` |
| 178 | - etc. |
| 179 | |
| 180 | ### Memory Integration |
| 181 | ```bash |
| 182 | # Store successful patterns |
| 183 | npx @claude-flow/cli memory store --namespace browser-patterns --key "login-flow" --value "snapshot->fill->click->wait" |
| 184 | |
| 185 | # Retrieve before similar task |
| 186 | npx @claude-flow/cli memory search --query "login automation" |
| 187 | ``` |
| 188 | |
| 189 | ### Hooks |
| 190 | ```bash |
| 191 | # Pre-browse hook (get context) |
| 192 | npx @claude-flow/cli hooks pre-edit --file "browser-task.ts" |
| 193 | |
| 194 | # Post-browse hook (record success) |
| 195 | npx @claude-flow/cli hooks post-task --task-id "browse-1" --success true |
| 196 | ``` |
| 197 | |
| 198 | ## Tips |
| 199 | |
| 200 | 1. **Always use snapshots** - They're optimized for AI with refs |
| 201 | 2. **Prefer `-i` flag** - Gets only interactive elements, smaller output |
| 202 | 3. **Use refs, not selectors** - More reliable, deterministic |
| 203 | 4. **Re-snapshot after navigation** - Page state changes |
| 204 | 5. **Use sessions for parallel work** - Each session is isolated |
